IMPRovEIS PRnsERvE-JAR.

The Schedule referred to in these Letters Patent and making part o! thesame.

To all whom it 'may concern:

Be it known that I, NATHAN THOMPsoN, of the city of Brooklyn, E. D., inthe county of Kings, and State of New York, have invented a new and usefnlImprovement in Preserve-J ars, and other like vessels, of which thefollowing is a full, clear, and exact description, reference being hadto the accompanying drawing,- forming part of this specification, and inwhich- Figure 1 represents a verticalsection of apreservejarconstructedin accordance with my improvement;

Figure 2, an edge view of the cap-portion ofthe same; .and

Figure 3, a plan of said cap-portion.

Similar letters of reference indicate corresponding parts. r

This, my improvement,is applicable to preserve or pickle-jars and otherlike vessels, irrespcctive'fof the materialof which they are composed,but it will suffice here to refer to the same in connection with apreserve or pickle-jar; and

My invention consists in a certain novel construction of the ring aroundthe neck and mouth o'f the jar, and peculiarities in the construction ofthe cap and attachments thereto, whereby tightness, with every facilityfor opening andclosing the jar. together with Referring to theaccompanying drawing- "A represents Ythe body of a preserve orpickle-jar, around the neck and mouth a, of which is a metal ring, B,arranged to extend from above the upper edge of down to the junction ofthe neck with the body ofthe jar, and made with a swell, bwhich not onlygives increasedstrength, but serves to receive a large quantity, ofcement, which insures the neck' being without fail, or entirelysurrounded by the cement that serves to Vsecure the ling to the neckj.

The outer surface of the neck may be indented,`to\ add to the hold ofthe cement upon it, and, if desired, may be formed with teats, or thering be indented from the outside, to form projections, for the purposeof se curing to the ring a perfect concentric position relatively to theneck, and equalizng the thickness of cement all around the latter, whenfitting the ring to its place over the neck.

Said ring B is provided arbund the circumferential swelled portion b ofit, with outside hooks c, of which there may be two, three, or more, andthe same arranged at suitable distances apart, according-to the numberand disposition of certain inclines, with which the cap() is provided,as hereinafter described.

' This cap C, which is also of metal, is made to t or- 'lap over theupper and reduced portion of the ring B, and is raised in its centre toreceive within it a piece of col-kg, (l, which serves to guide and hold,in a soft or pliable manner, a rubber washer or ring e, lying around thecork, said rubber serving, when the cap is closed, to bear on the upperedge of the ring B, and hermet- `ically seal the jar.

' Aroundthe outside of the cap O, is arranged a series of inclines, f,which when the cap is fitted to its plece, enter between, and bysuitably turning said cap, pass under the hooks c of the ring B, and arethus made to draw the cap Vtight down to its seat on the ring.

By the'disposition of the inclines f, around the outside of the cap, itcan readily be seen whether the jar is closed or not. v

Holes g may also be made in theinclines or upper projections, from theirback ends, to pass wire or string through, for tying the cap to the jar,to prevent loss of the cap when unfastened, or during transportation.v

l The cap Gis detached, when lit is required to open the jar, ybyturning said cap in.a back direction, so as to work its inclines j' fromunder the hooks c, after which, the cap may be lifted oli'. l

To facilitate such detachment, also locking of the cap when putting iton, I rit on the top of it, sliding bars D D, arranged to lie parallelto each other, and capableof being closed so as to lie within thediameter of the cap, or of being extended beyond the latter in reverseVdirections, as represented by blue lines in fig.` 3, to form convenientholding-devices and levers for turning the cap, but which, when slid orshut in, form no objectionable protrusion from the cap.

These bars D D are held to their places, and guided by suitable strapsand ways, and arrested in their inner and outer movements by appropriateend-stops.`

Said slides D D may be restrained from slipping or too freely working,by springs s, 'arran ged under them, and bent up at their outer ends, toform stops to the bars, which, when slid out, not only form levers forturning the cap, but also levers to lift or prize said cap after thesame has been turned to unlock itfrom the jar.

Were it not for some such means as the bars D D, it might be necessaryto use a ring-wrench, slotted, to receive through it projections at theback of the incliues f, as Vrepresented by fred lines in'ig. 3.

I am awarethat hooks and inclineshave been used upon the caps of tinjars. These Ido not claim; but

What I do claim, and desire to secure by Letters Patent, is-

l. The ringB,'having a swell, b, furnished with hooks, and cemented to aglass or earthelrjar, in combination with the cap, furnished withinclides, all substantially as and for the purpose set forth.

2. The cap C, having iitted or' secured toit reverselysli ling bars D D,essentially as and for the purpose or purposes herein set forth.
